Allowing for longer sessions?

Hello!

We've noticed that sessions here in Knowi are quite short, making us log in many times in a day. Is there a setting for increasing the session duration? If not, it would be a nice feature :)

On a similar note, if a user creates a chart, for me to see it correctly I have to log out and in again. I guess you are aware of it, but it would also be nice if this wasn't the case.
